Introduction:

Decision tree is one of the methods used in decision-making process. It would graphically represent the available alternatives and states of nature. It would also mention the payoffs and probabilities of the alternatives. It helps to choose the best alternative that would give the best result among the alternatives.

a)

Expert Solution

Explanation of Solution

Given information:

Three decision alternatives:

1^st construct small stamping plant
2^nd construct medium stamping plant
3^rd construct stamping plant

Each decision has demand:

Low demand which have 20% probability
Low demand which have 80% probability
If firm build small facility and demand turn out to be low than NPV is $42,000,000
If firm build small facility and demand turn out to be high than either subcontract or expand greatly, if sub contract than NPV is $42,000,000 and if expand greatly than $48,000,000.
If firm build medium facility and demand turn out to be low than NPV is $22,000,000.
If firm build medium facility and demand turn out to be high than either it do nothing or expand, if sub contract than NPV is $46,000,000 and if expand greatly than $50,000,000.
If firm build large facility and demand turn out to be low than NPV is -$20,000,000.
If firm build large facility and demand turn out to be high than NPV is $72,000,000.

As per given information, construct the decision tree:

Loose Leaf for Operations Management (The Mcgraw-hill Series in Operations and Decision Sciences), Chapter 5.S, Problem 9P , additional homework tip 1

Now, calculate the value of payoff and monetary value in decision tree:

Loose Leaf for Operations Management (The Mcgraw-hill Series in Operations and Decision Sciences), Chapter 5.S, Problem 9P , additional homework tip 2

Analysis the decision from right to left:

In the decision tree, there are two decisions making; first decision is between small, medium and large and second decision is between high demand of small and medium build facilities.
If small facilities build with high demand then select expand greatly because the payoff of expand greatly is higher than subcontract. The payoff of expand greatly is $48,000,000 and place double slash (reject) on subcontract.
If large facility build with high demand then select expand, because the payoff of expand greatly is higher than do nothing. The payoff of expand is $50,000,000 place double slash (reject) on do nothing.

Calculate the product of the chance probabilities and their respective payoffs for the remaining branches:

If small facility build:

$Low demand= (Probability× NPVsmall,low)=(20%×$42,000,000)=$8,400,000$

$High demand= (Probability× NPVsmall,high)=(80%×$48,000,000)=$38,400,000$

If medium facility IS build:

$Low demand= (Probability× NPVmedium,low)=(20%×$22,000,000)=$4,400,000$

$High demand= (Probability× NPVmedium,high)=(80%×$50,000,000)=$40,000,000$

If large facility is build:

$Low demand= (Probability× NPVlarge,low)=(20%×−$20,000,000)=−$4,000,000$

$High demand= (Probability× NPVmedium,high)=(80%×$72,000,000)=$57,600,000$

Calculation of the expected value in each alternative:

If small facility build

$Expected value=(Low demand payoff+high demand payoff)=($8,400,000+$38,400,000)=$46,800,000$

If medium facility build

$Expected value=(Low demand payoff+high demand payoff)=($4,400,000+$40,400,000)=$44,400,000$

If large facility build

$Expected value=(Low demand payoff+high demand payoff)=(−$4,00,000+$57,600,000)=$53,600,000$

Here, it is obtained that large facility build have higher expected value, hence it should be selected. And small and medium facilities have to be rejected.

Medium	$22,000,000.00	$50,000,000.00	$22,000,000.00
Large	-$20,000,000.00	$72,000,000.00	-$20,000,000.00

Hence, the best decision according to Maximin decision is to select a small medium facility.

Summary Introduction

To determine: Expected value of perfect information (EVPI) and interpret it.

Expected value of perfect information: It is the rate that a person is willing to pay to gain access to perfect information. A common area which uses expected value of perfect information is the healthcare economy. This value tries to evaluate the expected cost of the uncertainty, which can be interpreted as the expected value of perfect information

The expected value of perfect information can be calculated by using below given formula:

$EVPI = Expected value with perfect information−Maximum EMV$

c)

Expert Solution

Answer to Problem 9P

Theexpected value of perfect information is $12,400,000.

Explanation of Solution

Calculate the expected value with perfection information or Expected payoff under certainty:

$EVwPI= ∑Max(Alternative payoff)× Probability state of nature =(42,000,000×20%)+($72,000,000×80%)=$66,000,000$

Calculate the expected value with perfect information:

$EVPI = Expected value with perfect information−Maximum EMV =$66,000,000−$53,600,000=$12,400,000$

Therefore, EVPI is $12,400,000.

d)

Expert Solution

Explanation of Solution

Explanation

Here we draw each alternative to P (high), low demand should be on the left hand side and high demand value on the right hand side:

	Next Year’s Demand
Alternative	Low	High
Small	$42,000,000.00	$48,000,000.00
Medium	$22,000,000.00	$50,000,000.00
Large	-$20,000,000.00	$72,000,000.00

Graph plot:

Loose Leaf for Operations Management (The Mcgraw-hill Series in Operations and Decision Sciences), Chapter 5.S, Problem 9P , additional homework tip 3

From the above graph, we can determine the value of P (high) where each alternative are optimal.

From the graph, we can obtain that small build facility is best option, because of higher expected value. For low value of P(high) while for higher and intermediate value of P(high) large is the best option.

Calculate the range needed to determine upper part of line intersects:

For each line, b is the slope of the line and x = P(High). The slope of each line $Right hand value−Left hand value$ .

Determination of equation:

Small build facility = 42+6P (because high demand $48 million which is subtracted with low demand value $42 million)

Large build facility =-20+92P (because high demand $72million which is subtracted with low demand value -$20million)

Determination of intersection between small and large

$42 + 6P=−20 + 92P6P – 92P = −20 – 42−86P = −62P = −62−86=0.7209$

Hence, the intersection between small and large is 0.7209.

Therefore, optimal range can be derived as:

Small: P (High) = 0 to < .7209

Large: P (High) > .7209 to 1.00

Agree or disagree with post On the surface, the numbers in financial statements do present a snapshot of a company's financial position and performance. However, just looking at the raw numbers often doesn't tell the whole story or reveal underlying trends and relationships that are crucial for making informed decisions. Think of it like looking at individual pieces of a puzzle. Each number is a piece, providing some information. But to see the complete picture – the company's overall financial health, its performance over time, how it compares to its peers, and its potential future – you need to assemble those pieces using different analytical tools. For example: Horizontal analysis helps us understand how specific financial statement items have changed over multiple periods. Is revenue growing? Are expenses increasing at a faster rate than sales? This reveals trends that a single year's numbers wouldn't show. Vertical analysis allows us to see the relative size of each item within…

What can you do in response to an insulting offer?

Agree or disagree with post If someone hits you with an insulting offer, the first thing to do is not take it personally. It’s normal to feel a little offended, but blowing up or shutting down won’t help your case. Better move is to stay calm and treat it like a misunderstanding or just the first step in the conversation. That way, you keep things respectful but still let them know the offer doesn’t sit right with you. It also helps to back up your response with facts. Bring in things like your experience, numbers, or any specific results you delivered. That can shift the conversation away from feelings and toward the value you bring. Agree or disagree with post

As per given information, construct the decision tree:

Loose Leaf for Operations Management (The Mcgraw-hill Series in Operations and Decision Sciences), Chapter 5.S, Problem 9P , additional homework tip 1

Now, calculate the value of payoff and monetary value in decision tree:

Loose Leaf for Operations Management (The Mcgraw-hill Series in Operations and Decision Sciences), Chapter 5.S, Problem 9P , additional homework tip 2

Analysis the decision from right to left:

In the decision tree, there are two decisions making; first decision is between small, medium and large and second decision is between high demand of small and medium build facilities.
If small facilities build with high demand then select expand greatly because the payoff of expand greatly is higher than subcontract. The payoff of expand greatly is $48,000,000 and place double slash (reject) on subcontract.
If large facility build with high demand then select expand, because the payoff of expand greatly is higher than do nothing. The payoff of expand is $50,000,000 place double slash (reject) on do nothing.

Calculate the product of the chance probabilities and their respective payoffs for the remaining branches:

If small facility build:

$Low demand= (Probability× NPVsmall,low)=(20%×$42,000,000)=$8,400,000$

$High demand= (Probability× NPVsmall,high)=(80%×$48,000,000)=$38,400,000$

If medium facility IS build:

$Low demand= (Probability× NPVmedium,low)=(20%×$22,000,000)=$4,400,000$

$High demand= (Probability× NPVmedium,high)=(80%×$50,000,000)=$40,000,000$

If large facility is build:

$Low demand= (Probability× NPVlarge,low)=(20%×−$20,000,000)=−$4,000,000$

$High demand= (Probability× NPVmedium,high)=(80%×$72,000,000)=$57,600,000$

Calculation of the expected value in each alternative:

If small facility build

$Expected value=(Low demand payoff+high demand payoff)=($8,400,000+$38,400,000)=$46,800,000$

If medium facility build

$Expected value=(Low demand payoff+high demand payoff)=($4,400,000+$40,400,000)=$44,400,000$

If large facility build

$Expected value=(Low demand payoff+high demand payoff)=(−$4,00,000+$57,600,000)=$53,600,000$

Here, it is obtained that large facility build have higher expected value, hence it should be selected. And small and medium facilities have to be rejected.

Calculate the expected value with perfect information:

$EVPI = Expected value with perfect information−Maximum EMV =$66,000,000−$53,600,000=$12,400,000$

Therefore, EVPI is $12,400,000.

Expert Solution

Explanation of Solution

Explanation

Here we draw each alternative to P (high), low demand should be on the left hand side and high demand value on the right hand side:

	Next Year’s Demand
Alternative	Low	High
Small	$42,000,000.00	$48,000,000.00
Medium	$22,000,000.00	$50,000,000.00
Large	-$20,000,000.00	$72,000,000.00

Graph plot:

Loose Leaf for Operations Management (The Mcgraw-hill Series in Operations and Decision Sciences), Chapter 5.S, Problem 9P , additional homework tip 3

From the above graph, we can determine the value of P (high) where each alternative are optimal.

From the graph, we can obtain that small build facility is best option, because of higher expected value. For low value of P(high) while for higher and intermediate value of P(high) large is the best option.

Calculate the range needed to determine upper part of line intersects:

For each line, b is the slope of the line and x = P(High). The slope of each line $Right hand value−Left hand value$ .

Determination of equation:

Small build facility = 42+6P (because high demand $48 million which is subtracted with low demand value $42 million)

Large build facility =-20+92P (because high demand $72million which is subtracted with low demand value -$20million)

Determination of intersection between small and large

$42 + 6P=−20 + 92P6P – 92P = −20 – 42−86P = −62P = −62−86=0.7209$

Hence, the intersection between small and large is 0.7209.

Therefore, optimal range can be derived as:

Small: P (High) = 0 to < .7209

Large: P (High) > .7209 to 1.00

Explanation of Solution

Explanation

Here we draw each alternative to P (high), low demand should be on the left hand side and high demand value on the right hand side:

	Next Year’s Demand
Alternative	Low	High
Small	$42,000,000.00	$48,000,000.00

Graph plot:

Loose Leaf for Operations Management (The Mcgraw-hill Series in Operations and Decision Sciences), Chapter 5.S, Problem 9P , additional homework tip 3

From the above graph, we can determine the value of P (high) where each alternative are optimal.

From the graph, we can obtain that small build facility is best option, because of higher expected value. For low value of P(high) while for higher and intermediate value of P(high) large is the best option.

Calculate the range needed to determine upper part of line intersects:

For each line, b is the slope of the line and x = P(High). The slope of each line $Right hand value−Left hand value$ .

Determination of equation:

Small build facility = 42+6P (because high demand $48 million which is subtracted with low demand value $42 million)

Large build facility =-20+92P (because high demand $72million which is subtracted with low demand value -$20million)

Determination of intersection between small and large

$42 + 6P=−20 + 92P6P – 92P = −20 – 42−86P = −62P = −62−86=0.7209$

Hence, the intersection between small and large is 0.7209.

Therefore, optimal range can be derived as:

Small: P (High) = 0 to < .7209

Large: P (High) > .7209 to 1.00

Answer 25

Explanation of Solution

Calculate the expected value with perfection information or Expected payoff under certainty:

$EVwPI= ∑Max(Alternative payoff)× Probability state of nature =(42,000,000×20%)+($72,000,000×80%)=$66,000,000$

Calculate the expected value with perfect information:

$EVPI = Expected value with perfect information−Maximum EMV =$66,000,000−$53,600,000=$12,400,000$

Therefore, EVPI is $12,400,000.

Expert Solution

Explanation of Solution

Explanation

Here we draw each alternative to P (high), low demand should be on the left hand side and high demand value on the right hand side:

	Next Year’s Demand
Alternative	Low	High
Small	$42,000,000.00	$48,000,000.00
Medium	$22,000,000.00	$50,000,000.00
Large	-$20,000,000.00	$72,000,000.00

From the above graph, we can determine the value of P (high) where each alternative are optimal.

From the graph, we can obtain that small build facility is best option, because of higher expected value. For low value of P(high) while for higher and intermediate value of P(high) large is the best option.

Calculate the range needed to determine upper part of line intersects:

For each line, b is the slope of the line and x = P(High). The slope of each line $Right hand value−Left hand value$ .

Determination of equation:

Small build facility = 42+6P (because high demand $48 million which is subtracted with low demand value $42 million)

Large build facility =-20+92P (because high demand $72million which is subtracted with low demand value -$20million)

Determination of intersection between small and large

$42 + 6P=−20 + 92P6P – 92P = −20 – 42−86P = −62P = −62−86=0.7209$

Hence, the intersection between small and large is 0.7209.

Therefore, optimal range can be derived as:

Small: P (High) = 0 to < .7209

Large: P (High) > .7209 to 1.00
